Hi,

Could you please teach the differense between S6E2C2AJ0AGB1000A and S6E2C2AJ0AGB10000?

Hi all, we use the following version of the Softune Workbench:
- F2MC-16 Family SOFTUNE Workbench V30L35
- Cpu information file version = 19,30,01_2010.07.15
in order to produce our final output (*.mhx) to deploy on our machines.
Due to the large number of  *.mhx to produce (we have several machines and models)
we developed an external automated build tool that call the Softune Workbench via command line after preparing all the necessary options. To be sure everything works we compare the .mhx file generated launching Softune manually vs the automated Tool. So far so good , we always got the same output. Recently, because space problems, we changed the compiler optimization level (General purpose optimization level) from Speed priority to Level 1. Now the outputs (*.mhx)  always differ between manual and automated build. We don't understand why beacuse the automated build tool parse the project file dinamically in order to retrieve all the configurations. It seems that changing optimization level cause some hidden operation (or parameter) in softune Environment we are not able to catch.  Any idea on that? Thanks for any help

Hi all,

We cannot find EOL MCU differences.

I undestood that these parts are EOLed and cannot ask easily, but customer would ike to have information.

it is helpful if someone asnwer the assemlby site and other differences (if any).

How to calculate almost full and almost empty flags of the Asynchronous FIFO? My design is refer the paper: http://www.sunburst-design.com/papers/CummingsSNUG2002SJ_FIFO1.pdf

Hello.

About Multifunction timer setting for starting PWM output

According to document(32-Bit_Microcontroller_FM4_Family_Peripheral_Manual_Timer_Part: 002-04858) on page474, this setting is following.

1.Initial setting Set FRT operating mode (FRT control register other than TCSA.STOP). Set OCU operating mode and initialize the output level (OCU control register other than OCSA.CST0 and OCSA.CST1). Set the OCCP compare value (writing the OCCP value).

2.Start FRT count operation (writing 0 to TCSA:STOP).

3.Enable OCU's operation (writing 1 to OCSA:CST0 and OCSA:CST1).

(question)

At that time, is there any problem if the processes of 2 and 3 are performed in reverse?

(2.Start FRT count <-> 3.Enable OCU's)

My customer has a concern as following.

“They think when timer count is started and is matched with trigger count before enable OCU's operation, PWM won’t be output.”

I have a created hardware communicating application using RS232 protocol in MFC. But as there is problem regarding voltage signal strength, i would like to shift from RS232 to TCP/IP.

Can anyone help me on this topic...?

Dear colleagues,

Recently I stumbled on former Cypress Semiconductors microcontroller, old type - CY96F613RB, on the board, which I am trying to revive. Suspect that the controller could have issues with firmware or memory, so thinking about reuploading the firmware. That should not be hard to do with ISP - there are 4 pins routed on the board, marked +5V, SIN, SOT, GND. SIN and SOT routed to pins 7 (SIN2) and 8 (SOT2). Also there is a debug port, from pin 17 (Debug I/F). I checked in the Infineon site, found two available ISP programmers, but not sure if any of them is compatible - for some reason I did not found the compatible ICs list for the programmers, as this controller is quite old - please, recommend the programmer for this particular controller.

Best regards

Dennis
